Man! To spend $6900 is tough, there product is so expensive. I think that is more then double then bob's unit. I tell you Bob could be making so many more. Its a shame someone couldn't replace him. I am very happy with the unit I just purchased tho. Humidity is holding very well(running bob's unit) 66 bottom to 64 top. Steady and all day long
also the other thing I don't like with their humidors, solid wood shelves. No air flow in between.
